The noise is spuratic and doesn't always happen.
Called the service center that we take my wife's car into (I don't work on my wife's Jeep.. that way I don't get in trouble when something goes wrong) and they said it's most likely the alternator pulley if it's more of a whine than a squeal. He said this is pretty common with the Jeeps.. so hopefully this is the situation. We'll see.
Thanks,
